A couple of relatively mild days are expected, but changes are on the way again.
A couple of weak systems will cross the region over the next couple of days, but aside from some clouds, the most noticeable impacts will be mild temperatures ahead of each of the systems. In fact, many parts of the region could top 50 degrees on Saturday. However, a stronger cold front will move through late Saturday, bringing an end to our mild weather. As that front moves offshore and colder air settles in, a wave of low pressure will ride along the front on Sunday. While it will stay well south and east of us, it should be close enough to spread in some light snow or snow showers during the day on Sunday, especially south of Boston. This won’t be a major snowstorm, but an inch or two may accumulate across parts of southeastern Massachusetts and Cape Cod. As the system pulls away, snow will end Sunday night, and we’ll clear out on Monday, setting up a very chilly day despite increasing sunshine.

Thursday night: Clear skies. Low 24-31.
Friday: Sunshine to start the clear, clouds start to move in during the afternoon. High 42-49.
Friday night: Mostly cloudy. Low 34-41 during the evening, temperatures rise a little overnight.
Saturday: Partly sunny. High 49-56, a little cooler across Cape Cod.
Saturday night: Becoming cloudy again, light snow or snow showers may develop towards daybreak. Low 21-28.
Sunday: Cloudy and colder with light snow or snow showers expected, especially south of Boston. High 27-34.
Sunday night: Mostly cloudy, light snow or snow showers ending. Low 8-15.
Monday: Cloudy early, skies start to clear out in the afternoon. High 18-25.
